Abstract: Efficient editing is enabled when a video material encoded as an interlaced signal is mixed during editing. A first video signal in a progressive mode is obtained. This first video signal is encoded. The first video signal or a second video signal obtained by reducing resolution and/or a frame rate of the first video signal is converted to an interlaced signal from a progressive signal such that a third video signal is obtained. The third video signal is encoded. Encoded data of the first video signal and encoded data of the third video signal are recorded to a recording medium.

Abstract: [Object] To make a preferable operation possible with a simple structure that does not require an operation member with a complicated mechanism. [Solving Means] A display process of displaying a setting screen for setting one of an adjustment position and a numerical value on the basis of a user operation and a control process of changing one of the adjustment position and the numerical value depending on a change of a position of a knob by the user operation on the setting screen displayed in the display process are included. In the display process, the knob that is moved on the slider by the user operation is displayed, and the position of the knob is set as a default position on the slider, when the user operation is not performed.

Abstract: Disclosed herein is an information processing apparatus including: a computation block configured, so as to make an error of a VBV occupation amount of a VBV occupation amount target picture next to base data that is variable-length encoded data to be replaced by replacing data greater than an actual value, to compute the VBV occupation amount of the VBV occupation amount target picture from a VBV delay of the VBV occupation amount target picture; and an encoding block configured to variable-length encode the replacing data on the basis of the VBV occupation amount of the VBV occupation amount target picture computed by the computation block.

Abstract: In an editing apparatus; overwriting data used for insertion editing on base data, which is segmented into each picture including data having a predetermined unit of data amount X, and includes variable-length encoded real data, is variable-length encoded; each picture is sequentially obtained as a target picture, and regarding the target picture, if an amount of the overwriting data is equal to X, the overwriting data is handled as insertion data as it is, otherwise, insertion data is created by adding stuffing data to the overwriting data so that the amount of the overwriting data can be equal to X; a filler having the same amount as a filler of the base data is added to the insertion data having the same total amount as the real data; and the resultant insertion data is added onto the base data.

Abstract: A recording apparatus includes: a buffer unit that accumulates input stream data; a file recording processing unit that records a file of the stream data which is accumulated in the buffer unit and management information which is used to manage the file in a recording medium; a buffer monitoring unit that monitors a free space of the buffer unit; and a file system control unit that controls time that updates the management information using the file recording processing unit based on the free space of the buffer unit which is notified by the buffer monitoring unit.
